GAS BURNER.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Original application filed December 1, 1903, flerial No. 188,383.Divided in part and this application filed July 18, 1905.

. Serial No. 270,266.

a citizen of the United States, residing in Elizabeth, in the county ofUnion and State of New Jersey, have invented certain new and usefulImprovements in Gas-Burners, of which the following is a specification.

This invention relates to gas-burners de signed for heating relativelylarge areas and its object is to provide at low costa durable andefficient burner of this class in which danger of interior explosionshall be eliminated and in which the parts may be readily assembled,repaired, and replaced.

The burner is intended principally to be used with a mixture of gas andair, either under the ordinary pressure of gas-works or under higherpressure produced by the usual means.

In carrying out my invention I form a burner in the form of a hollowring, which in the under side thereof which receive small lockingprojections formed upon the screen. Fig. 4 illustrates the preferredform of diaphragm.

The burner shown in the drawings is in the shape of a hollow ring andcomprises two annular portions 1 and 2, the former of troughlike orU-shape section and the latter in the form of a cap, secured by screws3, which extend down through the cap and within the body of the tubularportion 1 and are threaded into the bottom of the latter. The gas issupplied through an inlet 4, formed integral with said portion 1.

Between the cap portion and the lower portion 1 of the ring areinserted, preferably, two screens, one (designated as 5) of smalldiameter and fitting upon the inner rim 6 of the annular portion 1, andthe other screen 7 of larger diameter and fitting upon the outer rim 8of said annular portion 1. Each of said rims is formed with radiatingflutes or jets 9 10, the former made in the upper surface and the lattermade in the lower surface of the diaphragm. These flutes may be formedby corrugating an annular strip of metal, and they constitute outwardly'directed or radiating jets, through which the gas is discharged, saidjets being sufliciently fine to prevent the flame from entering thechamber 11 of the burner. Each flute may be of approximately the samecapacity from its inlet to its outlet end, although in some cases theoutlet endmay be a trifle smaller than the inlet end, as illustrated inFigs. 3 and 4 of my application filed Dec. 1, 1903, Serial No. 183,333,(Patent No. 766,636,) of which this application is in part a division.

Each diaphragm-ring is shown as formed upon each of its outer and inneredges with both upwardly and downwardly extending projections 12 and 13,the former engaging grooves 14, formed in the under surface of the cap,and the latter embracing the rims of the trough-like member 1, therebyto prevent displacement of the screens and cap.

It will be seen that the parts may be readily assembled and secured bythe screws 3 and that when either screen is burned out the cap may bereadily removed and a fresh screen substituted, the projections 12 and13 serving to position the screens and cap.

Fig. at shows the ring-burner provided with a screen, such as seen atFigs. 3 and 4 in said application and patent, in which the strip ofmetal or diaphragm is so corrugated that the flutes are more capaciousat their inlet ends than at their outlet ends, this form of flute or jetbeing proof against liability of entrance of fire into the tube andmaking a highly eflicient burner.

Having thus described my invention, I claim 1. A gas-burner in the formof a tubular ring comprising a body portion, a cap portion and aseparate intervening screen provided upon each edge with locking pojections, and consisting of an annulus formed with corrugat ons in itstop and bottom surfaces.

2. A gas-burner in the form of a tubular ring comprising an annular bodyportion of U-section and a cap, and a screen intervening between the capand the outer rim of the body portion, said screen having flutes in itstop and bottom surfaces, each flute larger at its inlet end than at itsoutlet end.

3. A gas-burner in the form of a tubular ring comprising an annularportion of U-section and a cap, and a separate screen provided withlooking projections and interven ing between the cap and the inner rimof the body portion, said screen having flutes in its top and bottomsurfaces, each flute larger at its inlet end than at its outlet end.

4. A gas-burner in the form of a tubular ring comprising a body portionand a cap portion, and rings corrugated to form screens interveningbetween the cap and the inner and outer rims of the body portion, saidscreens provided with means for locking the cap in position upon thebody.

5. A gas-burner in the form of a tubular ring comprising a body portionand a cap portion, and an intervening ring corrugated to form a screenand having means for locking the cap in position upon the body.

6. A gas-burner in the form of a tubular ring made in annularportions,with an intervening annular diaphragm formed of a strip ofsheet metal corrugated to form radiating flutes in its top and bottomsurfaces, each flute larger at its inlet end than at its outlet end.

7. A gas-burner in the form of a tubular ring made of annular portionswith an intervening ring corrugated to form a screen, said screen-ringformed with numerous locking projections to engage both of said annularportions.

8. A gas-burner in the form of a tubular ring made or" annular portionswith an intervening ring corrugated to form a screen, said screen-ringformed with numerous locking projections to engage both of said annularportions, and one of said annular portions having a circular groove toreceive the projections.

9. A gas-burner in the form of a tubular ring comprising a trough-likeportion and a cap, and an intervening screen in the form of an annulardiaphragm formed with radiating flutes, said screen formed upon itsunder side with projections which engage a rim of the trough-likeportion; and upon its top side with projections which engage an annulargroove formed in the cap.

10. A gas-burner in the form of a tubular ring comprising a trough-likeportion and a cap, and an intervening screen in the form of an annulardiaphragm formed with radiating flutes, one of said annular portionshaving a groove, and said screen having projections which engage saidgroove.

11. A gas-burner in the form of a tubular ring comprising annular bodyand cap portions, a screen intervening between said portions and formedwith radiating flutes, and a series of fastening devices extending fromsaid cap to said body portion within the latter and detachablyconnecting said portions together; said screen having sets ofprojections upon its top and bottom sides, and said body and capportions having means to engage said. projections.
